The company said the decision had been made as part of a strategic decision to focus on publishing. IDG's best known UK magazine is PC Advisor.
"All I'm saying is that IDG has gone through an internal reorganisation and has basically decided to stick to their core business. You can read into that what you like," said a spokesman for Precision Events.
He added that the show was aimed at a market "inbetween Computer Shopper and the old Which? Computer".
